Description
Respondents were asked about their level of difficulty seeing, even when wearing glasses.
Comparability
In 2010, this item was collected for sample adults who completed the Quality of Life (QOL) supplement (administered to approximately a quarter of sample adults). In 2011-2017, this item was collected for sample adults who completed the Adult Functioning and Disability (AFD) supplement (administered to a subset of sample adults). Beginning in 2018, this item was included on the sample adult questionnaire. Changes in survey design (e.g., quarters in which the information was collected) may affect raw frequencies, but do not affect comparability of the variable. As always, data users should use the prescribed IPUMS NHIS weights.
